I'm also a big fan of the Thermos Funtainer/Foogo bottles. My kids have 2 each and have got rid of all other bottles. Have got all my family and friends using them too.
They stay cold all day - great for summer, are really tough and easy to clean.
They can be pricey to outlay for, but well worth it.
Target has Dora and SpongeBob ones for about $22.
Harris Scarfe has different designs for about $27 (always on sale though).
Also available online in tons of designs. If you search ebay overseas, the USA has Cars, Littlest Pet Shop, Spiderman, Barbie, Backyardigans, Scooby Doo etc ones as well.
DD1 has had a Foogo (plain) one for 18mths at school etc and only has a few minor scratches on lid. Also have Dora and Barbie ones and after 6mths of constant use there is only minor scratching to pictures.
Loved them so much I got my own (Thermos Intek). Got mine online from USA but Target stocks them now too.
Thanks I have looked at the funtainer bottles just found an online sale for $16.00 too.
I completely forgot I have a foogoo sippy cup which we never use, and I was actually really disappointed in after I bought it. Partly because it doesn't hold much and it seemed a bit heavy for little hands to hold.
I might take it out again to see if my 11mth old will drink water from it.
I never really understood how the valve worked but I guess it's just to stop from spilling when travelling???
